EAST LANSING, MI -- Firefighters extinguished a blaze Sunday evening at an oft-frequented field on Michigan State University's north campus.

Fire engulfed a patch of weeds along the edge of Adams Field about 7 p.m., according to witnesses. Fire crews responded and extinguished the flames within about 15 minutes.

The cause of the fire was not known. Witness said no one was injured, but authorities were not immediately available for comment.

The field is situated along West Circle Drive adjacent to the MSU Music Building. It is named in honor of Walter Adams, the university's 13th president, who was an avid fan of the MSU Spartan Marching Band, which has long rehearsed and held pregame warm-ups on the field. Students and alumni often gather on the field, with hundreds -- if not thousands -- passing through each day.
